twisted, causing the cap to seal the siphon
tube against the bottom of the siphon cup. Re-
position cap to lift the siphon tube off the bot-
tom of the cup. The wax motors are activated

valves. If the timing is not correct, suspect a
bad wiring connection. Also, examine the link-
age of the acutuator arm and proper location
of the spring on the wax motor

speeds. Change the inertial switch if suds were
not detected.
